Lyman County, South Dakota

Single-family vs. condo trends, market pressure signals, and 5-year price history. Source: Redfin.

Low transaction volume. Lyman County, South Dakota averaged 1 sale in the latest reporting month, so YoY price moves can swing wildly between months and don't necessarily reflect market direction. Inventory + DOM + price-drop signals stay informative; the % change badges are suppressed below 10 monthly sales.

Rent + invest vs. buy + own — backtested

15-yr rolling history · S&P 500
Property type:
Upfront capital committed (both paths): $58K = 20% down + 3% closing on a $254K home
BUY + OWN
Median ending wealth $223K $136K real
Net gain on $58K upfront: $164K
Range: $223K → $223K
Wealth = home value (appreciated at 3%/yr) − remaining mortgage − 6% selling cost. Gain = wealth − upfront. Leveraged appreciation on full $254K asset comes from the 20% down.
RENT + INVEST
Median ending portfolio $591K $436K real
Net gain on $210K contributed: $381K
Range: $275K → $1.50M
Same upfront cash + each year's (own − rent) surplus invested in S&P 500 at actual annual returns. Median renter contributed $210K total.
Median wealth delta: $368K in favor of RENT + INVEST

Educational tool, not investment or real-estate advice. Past performance does not guarantee future results. Backtests use actual annual total returns including dividends from S&P 500 (Damodaran (NYU Stern) annual total return (with dividends), 1957-present.).

Buyer model: 30-yr fixed mortgage, P&I + property tax + insurance + maintenance (1% of value/yr) + HOA. Selling cost = 6%. Investor model: down payment + annual cashflow surplus invested in the chosen index at that calendar year's actual return.

Tax model: pre-tax comparison. Toggle "after-tax mode" to apply MID, SALT, LTCG, and the Sec 121 capital-gains exclusion.

This calculator does not adjust for: PMI (assumed 20%+ down), differential transaction costs by state, lifestyle factors (commute, schools, kids), illiquidity / forced-sale risk, or insurance availability constraints (e.g., FL/CA wildfire). Consult a fiduciary advisor and tax professional before acting on any of this.

State-grain HPI YoY + drawdown from peak is the cleanest free price-stress proxy. The national delinquency rate gives the macro mortgage-stress backdrop. True county-level mortgage delinquency lives in paid datasets (MBA NDS, CoreLogic LP).

When boomer-owner share is high, expect more inventory hitting the market over the next decade as homes transition. High vacancy + high old-stock often signals deferred-maintenance markets where buyers can negotiate.

Top 5 Destinations (where movers went)

  1. Brule, South Dakota — 22 returns

IRS Statistics of Income tracks county-to-county migration via tax-return change-of-address. Net migration uses the exemption count (a proxy for people, including dependents). True net flow can lag by 1–2 years vs. real-time movements.

Who's Moving In (Census ACS)

Source: Census ACS B07001 (5-year)
Inbound Movers (1 yr)
217
5.96% of pop. — moved here from outside the county
From Other States

1.37% of pop. — interstate inbound
From Abroad
23
moved into the county from outside the U.S.
Same House 1 Year Ago

stable residents

Census ACS asks where people lived 1 year ago, so this counts inbound movers but does not show outbound — true net migration would require IRS SOI parsing.
